Knot Tyer by Tie Fast

Only the Tie-Fast Knot Tyer ties the unique Gryp-Knot that can't come untied because the end is gripped by all turns of the knot. This means that the greater the tension applied, the tighter the grip. Gryp-Knots are far superior to clinch, barrel, blood and other commonly used knots which actually have only one turn holding their ends.
